Connectedness arguments in linear dynamics
2011This chapter presents some of the deepest, most beautiful and most useful results from linear dynamics. We obtain Ansari’s theorem that every power of a hypercyclic operator is hypercyclic, the Bourdon–Feldman theorem that every somewhere dense orbit is (everywhere) dense, the Costakis–Peris theorem that every multi-hypercyclic operator is hypercyclic,

Connectedness of Julia sets for a quadratic random dynamical system
Ergodic Theory and Dynamical Systems, 2003The paper studies the Julia set of random quadratic groups and in particular, conditions for Julia sets to be totally disconnected. Questions raising and proofs draw on two previous articles by \textit{R. Brück} [Pac. J. Math. 198, 347--372 (2001; Zbl 1045.37030) and J. Lond. Math. Soc., II. Ser. 61, 462--470 (2000; Zbl 1033.37026)]. Let \((c_n)\) be a

On the connectedness of the attainability set for lattice dynamical systems
Journal of Difference Equations and Applications, 2012We prove the Kneser property (i.e. the connectedness and compactness of the attainability set at any time) for lattice dynamical systems in which we do not know whether the property of uniqueness of the Cauchy problem holds or not. Using this property, we can check that the global attractor of the multivalued semiflow generated by such system is ...

Connectedness preserving distributed coordination control over dynamic graphs
Proceedings of the 2005, American Control Conference, 2005., 2005This paper presents a solution to the limited information rendezvous problem over dynamic interaction graphs. In particular, we show how we, by adding appropriate weights to the edges in the graphs, can guarantee that the graph stays connected. In previous work on graph-based coordination, connectedness have been assumed, and this paper thus shows how ...

Dynamic Connectedness in Emerging Asian Equity Markets
2018Abstract This chapter examines dynamic connectedness among emerging Asian equity markets as well as explores their linkages vis-a-vis other major global markets. We find that international equity markets are tightly integrated. Measuring connectedness based on a generalized Vector Autoregressive (VAR) model, more than half of all total forecast error ...

Image segmentation based on fuzzy connectedness using dynamic weights
IEEE Transactions on Image Processing, 2006Traditional segmentation techniques do not quite meet the challenges posed by inherently fuzzy medical images. Image segmentation based on fuzzy connectedness addresses this problem by attempting to capture both closeness, based on characteristic intensity, and "hanging togetherness," based on intensity homogeneity, of image elements to the target ...

Lindbladian Dynamics Generates Inter-system Connectedness in Psychological Phenomena
Open Systems & Information DynamicsExploring a general stratagem for the way that Nature operates, one finds that in a variety of phenomena of one’s experience these come into existence (only) thanks to the special way that two disparate systems, being parts of an open system, are coupled together. This connectedness is shown here to come about through a Lindbladian operator, such that

Essays on memory and dynamics of connectedness in bitcoin markets [PDF]
, 2020 This thesis sheds new light on the exogenous and endogenous determinants of volatility in Bitcoin prices across many major countries around the globe. Different empirical strategies are proposed to investigate and understand the complex behaviour of volatility, its movements and significant persistence.
